Cloud computing is the delivery of on-demand computing resources, such as servers, storage, networking, software, and analytics, over the internet on a pay-as-you-go basis. This model offers flexible scalability, reduced costs, and increased efficiency by allowing users to access a shared pool of configurable resources from anywhere, eliminating the need to manage physical infrastructure locally.

How it Works

Remote Servers: Instead of running applications and storing data on local devices, cloud computing uses a network of remote servers and data centers to host and process information.

Internet Access: Users connect to these services and resources over the internet, accessing them from any device with a network connection.

On-Demand Resources: Users can provision and release computing resources as needed, with the cloud provider managing the underlying infrastructure.

Cloud computing models typically exhibit these five essential characteristics:

On-Demand Self-Service: Users can provision resources automatically without human intervention from the service provider.

Broad Network Access: Services are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms.

Resource Pooling: The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with resources dynamically assigned.

Rapid Elasticity: Capabilities can be elastically provisioned and released in some cases automatically to scale rapidly outward and inward commensurate with demand.

Measured Service: Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction.
